W3 Total Cache HELP

  • Hi as title states I need help with W3 Total Cache.
    I have installed it but get this error message :

    Page caching is not available: /home/content/88/6940688/html/wordpress1/wp-content/advanced-cache.php is not installed. Either the /home/content/88/6940688/html/wordpress1/wp-content directory is not write-able or another caching plugin installed. This error message will automatically disappear once the change is successfully made.

    I have deleted super cache (my previous cache plugin)but still get this error. I have also installed Word Wall if that maybe hinders?

    Any pointers would be very much appreciated
    This is my site.

    Thanks in advance

  • Looks like an incomplete W3TC installation, you can deactivate/delete and reinstall to try and fix. You’ll also need to make sure that wp-content is writable and that all of WPSC’s files are deleted.

    Happy to help if you need it (we make W3TC): https://www.w3-edge.com/contact/

    Thanks Willie,

    That seems to have worked but I still have various elements that it won’t let me use. This is what was flagged for compat check.

    Memcache extension: Not installed
    HTML Tidy extension: Not installed (required for HTML Tidy minifier suppport)
    Mime type detection: Not installed (required for CDN support)

    mod_deflate: Not detected (required for Page Cache (enhanced mode) and Browser Cache)
    mod_env: Not detected (required for Page Cache (enhanced mode) and Browser Cache)
    mod_expires: Not detected (required for Page Cache (enhanced mode) and Browser Cache)
    mod_headers: Not detected (required for Page Cache (enhanced mode) and Browser Cache)
    mod_mime: Not detected (required for Page Cache (enhanced mode) and Browser Cache)
    mod_rewrite: Not detected (required for Page Cache (enhanced mode) and Browser Cache)
    mod_setenvif: Not detected (required for Page Cache (enhanced mode) and Browser Cache)

    Sorry for long list but how do I remedy this?

    Many thanks in advance

    The first two are not typically found in shared hosting accounts, you’d need a VPS or dedicated server in order to be able to use/install those.

    The other headers aren’t necessarily not working/available, W3TC just can’t detect them. You can ask your host if they’re enabled for your account.

    Thanks again Willie.
    Just trying to make sure I have everything on that should be.
    At the moment I haven’t noticed much of a speed increase.

    I understand that if a function isn’t enabled it means I am missing software or my installation is not compatible but quite a few seem not to be enabled.

    Minify, Database cache, Object cache,CDN, Varnish are all not enabled.
    Can I get any of these working? If so how?

    My site is a portfolio/blog so is high in image content (that have been saved for web and smushed) I am also runnig BJ Lazy Load.

    I am just looking to find the correct settings for your plugin combined with the correct accompaniment of other plugins.

    Many thanks in advance for all your help

    You can use all of them, but I’d advise against enabling database and object caching unless you are caching against an opcode like APC or memcached.

    Minify can be used, you have to experiment with settings. Check the FAQ page in the plugin for documentation.

    Note that enabling minify might break your layout or site functionality if your setting are not correct. Not all code can be minified.
